Abstract

The invention relates to a type of shock and vibration isolator which has almost identical rigidity and damping properties in any translatory direction, wherein the device is disposed between a reference object (A) which is subjected to vibrations and shocks, and a means (B) which is only to be subjected to translatory damped vibrations and shocks in all directions, where a center bar (2) and wire rope holders (3) are designed for attachment to any one of the reference objects (A) or (B), characterized in that the center bar (2) and the wire rope holders (3) are rigidly interconnected to three or more independent wire rope series (4), each of which is formed of two or more wire rope loops where the configuration of a wire rope series (4) is based on essentially as many wire rope loops with opposite geometrical angles of inclination (A1 and A2), each wire rope series forming a symmetry along a center axis relative to an unloaded neutral position for the isolator and where the three or more wire rope series (4) are symmetrically arranged about the center axis in an about-axis symmetry principle relative to the radial neutral position of an unloaded isolator, such that the two symmetr…
